Cost of Solar Batteries Perth

Cost of Solar Batteries Perth - Many of us in the solar business, as well as many solar PV system users, have been waiting for the day when solar home battery prices would go low enough to provide a decent financial return. If you are seeking the Cost of Solar Batteries Perth, you should only stay with us since we provide all the real information about Solar Batteries.

Cost of Solar Batteries Perth

So, are solar batteries worth it in Perth right now?

Unfortunately, there is no black-and-white solution to this because it is dependent on your specific situation. In many circumstances, and strictly from an ROI standpoint, no. They have a rather high initial cost and (usually) a 10-year warranty, so they will most likely need to be replaced before they reach their pay-back time.

Some solar batteries come with warranties that go much beyond the industry norm of ten years. The new SENEC Home V3 Hybrid, for example, comes with a 20-year extended warranty. Receiving a respectable ROI in 20 years is significantly more attainable, especially when combined with government incentives.

How do solar batteries work?

Before we get started, let's go over how a solar battery works. Solar panels create electricity during the day while the sun shines. This electricity is first used to meet the demands of the residents and any excess energy is normally exported back into the grid. Some energy retailers provide a 'feed-in tariff,' which allows them to buy energy back from customers.

Surplus electricity can be used to charge a battery instead of being sent back into the grid. The home battery storage system may then be discharged in the evening to power household appliances. It can be exported back into the grid at peak demand times for a higher feed-in tariff (usually through a Virtual Power Plant scheme).

Solar power batteries store energy in direct current (DC). Batteries can be linked to a hybrid solar inverter through DC connections. Some batteries have an inverter (for example, the Tesla Powerwall) and may therefore be connected to the main power supply like any other AC equipment. More information on AC and DC connectors for solar battery storage may be found here.

How much cost of Solar Batteries Perth?

The age-old question, "How much do batteries cost?" is difficult to answer since there are various variables at play when installing a battery, all of which can affect the cost. Because there are several things to consider, the cost of solar panel storage batteries will vary. This table was put together to give you a general sense of pricing. Please keep in mind that these figures do not include installation costs. You should get an exact estimate from your installation company.

Battery Size Average Cost
2kWh $1,700
3.5kWh $5,000
6kWh $7,000
8.5kWh $10,000
10kWh $13,000
14kWh $15,000


The world is evolving. International agreements, global corporate attitudes, and public awareness are all urging us to transition to a low-carbon economy. Knowing the influence our spending patterns have on the earth and the security of future generations, minimizing your dependency on the grid is a significant step toward lowering your carbon footprint.

In short, why not if money isn't an issue and/or you can afford the repayments? Install as many panels as your roof will allow - the more you create, the more you will be able to meet the rest of your energy consumption demands. If you can afford a $10,000 TV with a $0 ROI or a $20,000 vacation, why not invest in your house and reduce your carbon footprint? It all boils down to your beliefs and choices—what makes sense for you may not make sense for someone else.

Factors that Add to the Cost of Solar Batteries  in Perth

When it comes to solar batteries, there is no one-size-fits-all solution. When it comes to solar electricity, several features may drive up the expenses, so make sure you're only paying for what you need.


We're not just talking about physical dimensions here. Batteries are classified according to their wattage, and the more power they can store, the more expensive they are.


Solar batteries must be connected to your solar power system, but they cannot be exposed to the elements. You'll need a dry, covered location to keep them, preferably near the electrical switchboard or inverter.

If you don't already have a shed or garage building, or if you need to add electrical lines to your solar battery placement, this can raise your expenditures.


An inverter is responsible for converting the electricity generated by solar panels into energy that may be stored in a solar battery. If you already have solar panels, your provider will have built an inverter so you can use the electricity.

However, if your system is outdate or not set up for energy storage, you may need to change the inverter or use a different coupling approach to connect your battery.


A licensed and insured solar power installer should handle the Cost of Solar Batteries in Perth. Attempting to repair your current solar power system on your own might result in harm to the system, the batteries, and you. Installations can take up to 2-3 hours, and labor expenses may be paid separately from the battery itself. If you need to make adjustments to your existing system, such as installing a new inverter, the task will take longer and will most certainly cost more.


The materials used to construct solar batteries have an impact on cost as well. The kind is also important to consider, from the hard costs of chemicals to the lifespan and cost of replacement. Solar batteries are classified into five categories, however, only two are employe in home solar systems:

  • Lead-acid batteries are less expensive, contain dangerous compounds, and may last up to 8 years.
  • Lithium-ion batteries are more costly, can include organic components, and have a lifespan of up to ten years.

Frequently Asked Questions

Q - What is the cost of a 5kw Solar Battery in Perth?

A - The cost of a battery system for a 5kW solar panel is between $1,300 and $2,000 per kWh. Therefore, for a 5kW system, the total cost of battery storage can range from $7,000 to $10,000.

Q - How long can the solar battery be used?

A - The lifetime of the lithium-ion batteries used in most contemporary home solar power systems is comparable to that of typical lead-acid batteries. Solar batteries should last anywhere from five to fifteen years.
